With Anderlecht and Celtic also in the pool, the PSG-Bayern clash at Paris' Parc de Princes on Wednesday could well decide the winner of Group B.
'Paris have certainly given out a few more euros than us, but money doesn't score goals, quality on the pitch scores goals, good teams score goals,' said veteran winger Robben before the team jetted to Paris.
Team not players for Robben
But when asked about PSG's star-studded MCN attack - Mbappe, Edinson Cavani and Neymar - Robben was unphased: 'The important thing is the performance of the team, not just to focus on particular players'.
'I know our team, they are highly motivated and concentrated for games like this,' said the former striker. I am convinced we can get something out of this game.'

'Of course, that is an attack with world-class players, we have to control that, but we have more experience,' countered Rummenigge.
